Error: too many outputs

function ForwardSub(L,b)
    %Forward substitution method to compute Y= L/b
    
    s = length(b); %no of coloumns
    
    Y = zeros(s,1); %the answer Y is initialized to zero
    
    Y(1) = b(1)/L(1,1); %the first diagonal entry
    
    for j=2:s
        Y(j)=b(j) - sum(L(j, 1:j-1)).*Y(1:j-1)/L(j,j); %solve for other elements of Y
    end
end

function Y = ForwardSub(L,b) % you forgot to assign the output in the function definition
